Discotics studied by EPR: The application of EPR spectroscopy to columnar discoticliquidcrystals using a novel rigid‐core nitroxide spin probe (see picture) is possible. EPR spectra measured at different temperatures across three phases of hexakis(n‐hexyloxy)triphenylene show a strong sensitivity to the phase composition, molecular rotational dynamics, and columnar order.
